This image shows that the poet wishes that his intimate connection with nature should be so lasting and permanent that everyday of his life can be connected with the other by the link of natural love. He compares days to ring of a chain. Its rings are linked together strongly. The word "wish" shows the poet's keen desire and hope to spend the rest of his life attached to nature. He yearns to have the love of nature to the end of his life. This reflects the poet's strong love for nature. The poet uses verb to be in different tenses or forms.
